CMS e-lab Workshop: We held a 2-day QuarkNet CMS e-lab Workshop at UCR on July 14 and 15, 2016 with two teachers participating as well as a QuarkNet Leadership Fellow (Robert Baker). Shane Wood from QuarkNet used the opportunity to try out a new version of the CMS e-lab software, and the teachers benefited greatly from this. A lot of feedback was provided to Shane over the two days.

Day one of the 2-day workshop started with the opportunity for teachers to chat and ask the mentors LHC-related questions, followed by working through two activities from QuarkNet's data portfolio: Mass of the Z and CMS Data Express. Teachers were introduced to both the original CMS e-Lab site, along with the new site under development. Day two of this workshop began with time for the teachers to work on particular investigation in the e-Lab and build an accompanying online poster. While working, the teachers noted problems with the e-Lab and aspects they appreciated; both helpful in making the new site more useful and user-friendly. The teachers presented their poster upon completion of their investigation, then discussed classroom implementation.

The main activity of the University of California at Riverside QuarkNet center in 2014 was its particiaption in International Masterclasses. Approximately 30 students participated: 12 from San Jacinto High School and 18 from Riverside Preparatory Academy. UCR participated in the ATLAS Z measurement. As usual, mentor Bill Gary and his colleagues were careful to teach the students to accept all lepton candidate events irrespective of whether they thought the dilepton system formed a good Z boson candidate or not. As a result. they successfully also found the J/Ψ and Upsilon mesons, as well as the simulated Z-prime resonance the ATLAS masterclass developers added in at ~1000 GeV. Also as usual, UCR had a CERN-moderated videoconference in spite of the tme difference. It was again a great success, as the students really enjoyed interacting with their peer high school students in Europe.
